| Abstract: | It is difficult to deduce the degree of freedom of an image (DOF ) from the theory of the resolving power. This paper has elementally described the relation of modulation transfer function with prolate spheroidal wave function and its eigen value,and tries to do some fundamental work to overcome the difficulty of applying the theory of DOF to analyze an optical system |

| Keywords: | Degree of freedom of an image Prolate spheroidal wave function |
